Key Facts
- A new species of Cricket named Indimimus jayanti was found in the Kurra caves of Chhattisgarh.
- It is identified under the genus Arachnomimus Saussure, 1897.
- The newly discovered Cricket is different from the two subgenera, Arachnomimus and Euarachnomimus, because of the male genitalia structure.
- Crickets are noticeable for their loud calls.
- But newly found Cricket males of the new Jayanti subgenus cannot produce sound and their females don’t have ears.
Arachnomimus Saussure, 1897
- Arachnomimus is the genus name given to crickets that resembled spiders.
- Crickets of this group are commonly called spider crickets because of their smaller body size and long legs.
Why this discovery is Significant ?
- Male crickets produce this sound by rubbing their wings against each other to attract females.
- The females listen to these calls using ears located on their legs and approach the males for mating and reproduction.
- But Jayanti do not have such capabilities.
- The crickets were found on the walls of the Kurra caves which don’t have light inside.
- They may communicate with vibration sounds which can be used in hearing aids.
Crickets Spider
- Most commonly they are found in forest environments or within caves, animal burrows, cellars, under stones, or in wood or similar environments.
- Typically living in a lightless environment, or active at night, they rely heavily on their sense of touch.
